# Pact Spring/JUnit5 Support
This module extends the base [Pact JUnit5 module](../pact-jvm-provider-junit5). See that for more details.
For writing Spring Pact verification tests with JUnit 5, there is an JUnit 5 Invocation Context Provider that you can use with
the `@TestTemplate` annotation. This will generate a test for each interaction found for the pact files for the provider.
To use it, add the `@Provider` and `@ExtendWith(SpringExtension.class)` and one of the pact source annotations to your test class (as per a JUnit 5 test), then
add a method annotated with `@TestTemplate` and `@ExtendWith(PactVerificationSpringProvider.class)` that
takes a `PactVerificationContext` parameter. You will need to call `verifyInteraction()` on the context parameter in
your test template method.
For example:
```java
@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
@Provider("Animal Profile Service")
@PactBroker
public class ContractVerificationTest {
@TestTemplate
@ExtendWith(PactVerificationSpringProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
}
```
You will now be able to setup all the required properties using the Spring context, e.g. creating an application
YAML file in the test resources:
```yaml
pactbroker:
host: your.broker.host
auth:
username: broker-user
password: broker.password
```
You can also run pact tests against `MockMvc` without need to spin up the whole application context which takes time
and often requires more additional setup (e.g. database). In order to run lightweight tests just use `@WebMvcTest`
from Spring and `MockMvcTestTarget` as a test target before each test.
For example:
```java
@WebMvcTest
@Provider("myAwesomeService")
@PactBroker
class ContractVerificationTest {
@Autowired
private MockMvc mockMvc;
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
@BeforeEach
void before(PactVerificationContext context) {
context.setTarget(new MockMvcTestTarget(mockMvc));
}
}
```
You can also use `MockMvcTestTarget` for tests without spring context by providing the controllers manually.
For example:
```java
@Provider("myAwesomeService")
@PactFolder("pacts")
class MockMvcTestTargetStandaloneMockMvcTestJava {
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
@BeforeEach
void before(PactVerificationContext context) {
MockMvcTestTarget testTarget = new MockMvcTestTarget();
testTarget.setControllers(new DataResource());
context.setTarget(testTarget);
}
@RestController
static class DataResource {
@GetMapping("/data")
@ResponseStatus(HttpStatus.NO_CONTENT)
void getData(@RequestParam("ticketId") String ticketId) {
}
}
}
```
**Important:** Since `@WebMvcTest` starts only Spring MVC components you can't use `PactVerificationSpringProvider`
and need to fallback to `PactVerificationInvocationContextProvider`

# Pact Junit 5 Extension
## Overview
For writing Pact verification tests with JUnit 5, there is an JUnit 5 Invocation Context Provider that you can use with
the `@TestTemplate` annotation. This will generate a test for each interaction found for the pact files for the provider.
To use it, add the `@Provider` and one of the pact source annotations to your test class (as per a JUnit 4 test), then
add a method annotated with `@TestTemplate` and `@ExtendWith(PactVerificationInvocationContextProvider.class)` that
takes a `PactVerificationContext` parameter. You will need to call `verifyInteraction()` on the context parameter in
your test template method.
For example:
```java
@Provider("myAwesomeService")
@PactFolder("pacts")
public class ContractVerificationTest {
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
}
```
For details on the provider and pact source annotations, refer to the [Pact junit runner](../pact-jvm-provider-junit/README.md) docs.
## Test target
You can set the test target (the object that defines the target of the test, which should point to your provider) on the
`PactVerificationContext`, but you need to do this in a before test method (annotated with `@BeforeEach`). There are three
different test targets you can use: `HttpTestTarget`, `HttpsTestTarget` and `AmpqTestTarget`.
For example:
```java
@BeforeEach
void before(PactVerificationContext context) {
context.setTarget(HttpTestTarget.fromUrl(new URL(myProviderUrl)));
// or something like
// context.setTarget(new HttpTestTarget("localhost", myProviderPort, "/"));
}
```
## Provider State Methods
Provider State Methods work in the same way as with JUnit 4 tests, refer to the [Pact junit runner](../pact-jvm-provider-junit/README.md) docs.
## Modifying the requests before they are sent
**Important Note:** You should only use this feature for things that can not be persisted in the pact file. By modifying the request, you are potentially modifying the contract from the consumer tests!
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would be authentication tokens, which have a small life span. The Http and Https test targets support injecting the request that will executed into the test template method.
You can then add things to the request before calling the `verifyInteraction()` method.
For example to add a header:
```java
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void testTemplate(PactVerificationContext context, HttpRequest request) {
// This will add a header to the request
request.addHeader("X-Auth-Token", "1234");
context.verifyInteraction();
}
```
## Objects that can be injected into the test methods
You can inject the following objects into your test methods (just like the `PactVerificationContext`). They will be null if injected before the
supported phase.
| Object | Can be injected from phase | Description |
| ------ | --------------- | ----------- |
| PactVerificationContext | @BeforeEach | The context to use to execute the interaction test |
| Pact | any | The Pact model for the test |
| Interaction | any | The Interaction model for the test |
| HttpRequest | @TestTemplate | The request that is going to be executed (only for HTTP and HTTPS targets) |
| ProviderVerifier | @TestTemplate | The verifier instance that is used to verify the interaction |

pact-jvm-provider_2.12 from group au.com.dius (version 3.6.15)
Pact provider
=============
sub project of https://github.com/DiUS/pact-jvm
The pact provider is responsible for verifying that an API provider adheres to a number of pacts authored by its clients
This library provides the basic tools required to automate the process, and should be usable on its own in many instances.
Framework and build tool specific bindings will be provided in separate libraries that build on top of this core functionality.
### Provider State
Before each interaction is executed, the provider under test will have the opportunity to enter a state.
Generally the state maps to a set of fixture data for mocking out services that the provider is a consumer of (they will have their own pacts)
The pact framework will instruct the test server to enter that state by sending:
POST "${config.stateChangeUrl.url}/setup" { "state" : "${interaction.stateName}" }
### An example of running provider verification with junit
This example uses Groovy, JUnit 4 and Hamcrest matchers to run the provider verification.
As the provider service is a DropWizard application, it uses the DropwizardAppRule to startup the service before running any test.
**Warning:** It only grabs the first interaction from the pact file with the consumer, where there could be many. (This could possibly be solved with a parameterized test)
```groovy
class ReadmeExamplePactJVMProviderJUnitTest {
@ClassRule
public static TestRule startServiceRule = new DropwizardAppRule<DropwizardConfiguration>(
TestDropwizardApplication.class, ResourceHelpers.resourceFilePath("dropwizard/test-config.yaml"))
private static ProviderInfo serviceProvider
private static Pact<RequestResponseInteraction> testConsumerPact
private static ConsumerInfo consumer
@BeforeClass
static void setupProvider() {
serviceProvider = new ProviderInfo("Dropwizard App")
serviceProvider.setProtocol("http")
serviceProvider.setHost("localhost")
serviceProvider.setPort(8080)
serviceProvider.setPath("/")
consumer = new ConsumerInfo()
consumer.setName("test_consumer")
consumer.setPactSource(new UrlSource(
ReadmeExamplePactJVMProviderJUnitTest.getResource("/pacts/zoo_app-animal_service.json").toString()))
testConsumerPact = PactReader.loadPact(consumer.getPactSource()) as Pact<RequestResponseInteraction>
}
@Test
void runConsumerPacts() {
// grab the first interaction from the pact with consumer
Interaction interaction = testConsumerPact.interactions.get(0)
// setup the verifier
ProviderVerifier verifier = setupVerifier(interaction, serviceProvider, consumer)
// setup any provider state
// setup the client and interaction to fire against the provider
ProviderClient client = new ProviderClient(serviceProvider, new HttpClientFactory())
Map<String, Object> failures = new HashMap<>()
verifier.verifyResponseFromProvider(serviceProvider, interaction, interaction.getDescription(), failures, client)
if (!failures.isEmpty()) {
verifier.displayFailures(failures)
}
// Assert all good
assertThat(failures, is(empty()))
}
private ProviderVerifier setupVerifier(Interaction interaction, ProviderInfo provider, ConsumerInfo consumer) {
ProviderVerifier verifier = new ProviderVerifier()
verifier.initialiseReporters(provider)
verifier.reportVerificationForConsumer(consumer, provider)
if (!interaction.getProviderStates().isEmpty()) {
for (ProviderState providerState: interaction.getProviderStates()) {
verifier.reportStateForInteraction(providerState.getName(), provider, consumer, true)
}
}
verifier.reportInteractionDescription(interaction)
return verifier
}
}
```
### An example of running provider verification with spock
This example uses groovy and spock to run the provider verification.
Again the provider service is a DropWizard application, and is using the DropwizardAppRule to startup the service.
This example runs all interactions using spocks Unroll feature
```groovy
class ReadmeExamplePactJVMProviderSpockSpec extends Specification {
@ClassRule @Shared
TestRule startServiceRule = new DropwizardAppRule<DropwizardConfiguration>(TestDropwizardApplication,
ResourceHelpers.resourceFilePath('dropwizard/test-config.yaml'))
@Shared
ProviderInfo serviceProvider
ProviderVerifier verifier
def setupSpec() {
serviceProvider = new ProviderInfo('Dropwizard App')
serviceProvider.protocol = 'http'
serviceProvider.host = 'localhost'
serviceProvider.port = 8080
serviceProvider.path = '/'
serviceProvider.hasPactWith('zoo_app') {
pactSource = new FileSource(new File(ResourceHelpers.resourceFilePath('pacts/zoo_app-animal_service.json')))
}
}
def setup() {
verifier = new ProviderVerifier()
}
def cleanup() {
// cleanup provider state
// ie. db.truncateAllTables()
}
def cleanupSpec() {
// cleanup provider
}
@Unroll
def "Provider Pact - With Consumer #consumer"() {
expect:
verifyConsumerPact(consumer).empty
where:
consumer << serviceProvider.consumers
}
private Map verifyConsumerPact(ConsumerInfo consumer) {
Map failures = [:]
verifier.initialiseReporters(serviceProvider)
verifier.runVerificationForConsumer(failures, serviceProvider, consumer)
if (!failures.empty) {
verifier.displayFailures(failures)
}
failures
}
}
```

# Pact Spring/JUnit runner
## Overview
Library provides ability to play contract tests against a provider using Spring & JUnit.
This library is based on and references the JUnit package, so see the [Pact JUnit 4](../pact-jvm-provider-junit) or [Pact JUnit 5](../pact-jvm-provider-junit5) providers for more details regarding configuration using JUnit.
Supports:
- Standard ways to load pacts from folders and broker
- Easy way to change assertion strategy
- Spring Test MockMVC Controllers and ControllerAdvice using MockMvc standalone setup.
- MockMvc debugger output
- Multiple @State runs to test a particular Provider State multiple times
- **au.com.dius.pact.provider.junit.State** custom annotation - before each interaction that requires a state change,
all methods annotated by `@State` with appropriate the state listed will be invoked.
**NOTE:** For publishing provider verification results to a pact broker, make sure the Java system property `pact.provider.version`
is set with the version of your provider.
## Example of MockMvc test
```java
@RunWith(RestPactRunner.class) // Custom pact runner, child of PactRunner which runs only REST tests
@Provider("myAwesomeService") // Set up name of tested provider
@PactFolder("pacts") // Point where to find pacts (See also section Pacts source in documentation)
public class ContractTest {
//Create an instance of your controller. We cannot autowire this as we're not using (and don't want to use) a Spring test runner.
@InjectMocks
private AwesomeController awesomeController = new AwesomeController();
//Mock your service logic class. We'll use this to create scenarios for respective provider states.
@Mock
private AwesomeBusinessLogic awesomeBusinessLogic;
//Create an instance of your controller advice (if you have one). This will be passed to the MockMvcTarget constructor to be wired up with MockMvc.
@InjectMocks
private AwesomeControllerAdvice awesomeControllerAdvice = new AwesomeControllerAdvice();
//Create a new instance of the MockMvcTarget and annotate it as the TestTarget for PactRunner
@TestTarget
public final MockMvcTarget target = new MockMvcTarget();
@Before //Method will be run before each test of interaction
public void before() {
//initialize your mocks using your mocking framework
MockitoAnnotations.initMocks(this);
//configure the MockMvcTarget with your controller and controller advice
target.setControllers(awesomeController);
target.setControllerAdvice(awesomeControllerAdvice);
}
@State("default", "no-data") // Method will be run before testing interactions that require "default" or "no-data" state
public void toDefaultState() {
target.setRunTimes(3); //let's loop through this state a few times for a 3 data variants
when(awesomeBusinessLogic.getById(any(UUID.class)))
.thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.ONE))
.thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.TWO))
.thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.THREE));
}
@State("error-case")
public void SingleUploadExistsState_Success() {
target.setRunTimes(1); //tell the runner to only loop one time for this state
//you might want to throw exceptions to be picked off by your controller advice
when(awesomeBusinessLogic.getById(any(UUID.class)))
.then(i -> { throw new NotCoolException(i.getArgumentAt(0, UUID.class).toString()); });
}
}
```
## Using a Spring runner (version 3.5.7+)
You can use `SpringRestPactRunner` instead of the default Pact runner to use the Spring test annotations. This will
allow you to inject or mock spring beans.
For example:
```java
@RunWith(SpringRestPactRunner.class)
@Provider("pricing")
@PactBroker(protocol = "https", host = "${pactBrokerHost}", port = "443",
authentication = @PactBrokerAuth(username = "${pactBrokerUser}", password = "${pactBrokerPassword}"))
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class PricingServiceProviderPactTest {
@MockBean
private ProductClient productClient; // This will replace the bean with a mock in the application context
@TestTarget
@SuppressWarnings(value = "VisibilityModifier")
public final Target target = new HttpTarget(8091);
@State("Product X010000021 exists")
public void setupProductX010000021() throws IOException {
reset(productClient);
ProductBuilder product = new ProductBuilder()
.withProductCode("X010000021");
when(productClient.fetch((Set<String>) argThat(contains("X010000021")), any())).thenReturn(product);
}
@State("the product code X00001 can be priced")
public void theProductCodeX00001CanBePriced() throws IOException {
reset(productClient);
ProductBuilder product = new ProductBuilder()
.withProductCode("X00001");
when(productClient.find((Set<String>) argThat(contains("X00001")), any())).thenReturn(product);
}
}
```
### Using Spring Context Properties (version 3.5.14+)
From version 3.5.14 onwards, the SpringRestPactRunner will look up any annotation expressions (like `${pactBrokerHost}`)
above) from the Spring context. For Springboot, this will allow you to define the properties in the application test properties.
For instance, if you create the following `application.yml` in the test resources:
```yaml
pactbroker:
host: "your.broker.local"
port: "443"
protocol: "https"
auth:
username: "<your broker username>"
password: "<your broker password>"
```
Then you can use the defaults on the `@PactBroker` annotation.
```java
@RunWith(SpringRestPactRunner.class)
@Provider("My Service")
@PactBroker(
authentication = @PactBrokerAuth(username = "${pactbroker.auth.username}", password = "${pactbroker.auth.password}")
)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class PactVerificationTest {
```
### Using a random port with a Springboot test (version 3.5.14+)
If you use a random port in a springboot test (by setting `SpringBootTest.WebEnvironment.RANDOM_PORT`), you can use the
`SpringBootHttpTarget` which will get the application port from the spring application context.
For example:
```java
@RunWith(SpringRestPactRunner.class)
@Provider("My Service")
@PactBroker
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class PactVerificationTest {
@TestTarget
public final Target target = new SpringBootHttpTarget();
}
```

the `@TestTemplate` annotation. This will generate a test for each interaction found for the pact files for the provider.
To use it, add the `@Provider` and one of the pact source annotations to your test class (as per a JUnit 4 test), then
add a method annotated with `@TestTemplate` and `@ExtendWith(PactVerificationInvocationContextProvider.class)` that
takes a `PactVerificationContext` parameter. You will need to call `verifyInteraction()` on the context parameter in
your test template method.
For example:
```java
@Provider("myAwesomeService")
@PactFolder("pacts")
public class ContractVerificationTest {
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
}
```
For details on the provider and pact source annotations, refer to the [Pact junit runner](../pact-jvm-provider-junit/README.md) docs.
## Test target
You can set the test target (the object that defines the target of the test, which should point to your provider) on the
`PactVerificationContext`, but you need to do this in a before test method (annotated with `@BeforeEach`). There are three
different test targets you can use: `HttpTestTarget`, `HttpsTestTarget` and `AmpqTestTarget`.
For example:
```java
@BeforeEach
void before(PactVerificationContext context) {
context.setTarget(HttpTestTarget.fromUrl(new URL(myProviderUrl)));
// or something like
// context.setTarget(new HttpTestTarget("localhost", myProviderPort, "/"));
}
```
**Note for Maven users:** If you use Maven to run your tests, you will have to make sure that the Maven Surefire plugin is at least
version 2.22.1 uses an isolated classpath.
For example, configure it by adding the following to your POM:
```xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.1</version>
<configuration>
<useSystemClassLoader>false</useSystemClassLoader>
</configuration>
</plugin>
```
## Provider State Methods
Provider State Methods work in the same way as with JUnit 4 tests, refer to the [Pact junit runner](../pact-jvm-provider-junit/README.md) docs.
### Using multiple classes for the state change methods
If you have a large number of state change methods, you can split things up by moving them to other classes. You will
need to specify the additional classes on the test context in a `Before` method. Do this with the `withStateHandler`
or `setStateHandlers` methods. See [StateAnnotationsOnAdditionalClassTest](pact-jvm-provider-junit5/src/test/java/au/com/dius/pact/provider/junit5/StateAnnotationsOnAdditionalClassTest.java) for an example.
## Modifying the requests before they are sent
**Important Note:** You should only use this feature for things that can not be persisted in the pact file. By modifying the request, you are potentially modifying the contract from the consumer tests!
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would be authentication tokens, which have a small life span. The Http and Https test targets support injecting the request that will executed into the test template method.
You can then add things to the request before calling the `verifyInteraction()` method.
For example to add a header:
```java
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void testTemplate(PactVerificationContext context, HttpRequest request) {
// This will add a header to the request
request.addHeader("X-Auth-Token", "1234");
context.verifyInteraction();
}
```
## Objects that can be injected into the test methods
You can inject the following objects into your test methods (just like the `PactVerificationContext`). They will be null if injected before the
supported phase.
| Object | Can be injected from phase | Description |
| ------ | --------------- | ----------- |
| PactVerificationContext | @BeforeEach | The context to use to execute the interaction test |
| Pact | any | The Pact model for the test |
| Interaction | any | The Interaction model for the test |
| HttpRequest | @TestTemplate | The request that is going to be executed (only for HTTP and HTTPS targets) |
| ProviderVerifier | @TestTemplate | The verifier instance that is used to verify the interaction |

or `setStateHandlers` methods. See [StateAnnotationsOnAdditionalClassTest](src/test/java/au/com/dius/pact/provider/junit5/StateAnnotationsOnAdditionalClassTest.java) for an example.
## Modifying the requests before they are sent
**Important Note:** You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would be
authentication tokens, which have a small life span. The Http and Https test targets support injecting the request that
will executed into the test template method.
You can then add things to the request before calling the `verifyInteraction()` method.
For example to add a header:
```java
@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void testTemplate(PactVerificationContext context, HttpRequest request) {
// This will add a header to the request
request.addHeader("X-Auth-Token", "1234");
context.verifyInteraction();
}
```
## Objects that can be injected into the test methods
You can inject the following objects into your test methods (just like the `PactVerificationContext`). They will be null if injected before the
supported phase.
| Object | Can be injected from phase | Description |
| ------ | --------------- | ----------- |
| PactVerificationContext | @BeforeEach | The context to use to execute the interaction test |
| Pact | any | The Pact model for the test |
| Interaction | any | The Interaction model for the test |
| HttpRequest | @TestTemplate | The request that is going to be executed (only for HTTP and HTTPS targets) |
| ProviderVerifier | @TestTemplate | The verifier instance that is used to verify the interaction |
## Allowing the test to pass when no pacts are found to verify (version 4.0.7+)
By default, the test will fail with an exception if no pacts were found to verify. This can be overridden by adding the
`@IgnoreNoPactsToVerify` annotation to the test class. For this to work, you test class will need to be able to receive
null values for any of the injected parameters.

Pact provider
=============
sub project of https://github.com/DiUS/pact-jvm
The pact provider is responsible for verifying that an API provider adheres to a number of pacts authored by its clients
This library provides the basic tools required to automate the process, and should be usable on its own in many instances.
Framework and build tool specific bindings will be provided in separate libraries that build on top of this core functionality.
### Provider State
Before each interaction is executed, the provider under test will have the opportunity to enter a state.
Generally the state maps to a set of fixture data for mocking out services that the provider is a consumer of (they will have their own pacts)
The pact framework will instruct the test server to enter that state by sending:
POST "${config.stateChangeUrl.url}/setup" { "state" : "${interaction.stateName}" }
### An example of running provider verification with junit
This example uses Groovy, JUnit 4 and Hamcrest matchers to run the provider verification.
As the provider service is a DropWizard application, it uses the DropwizardAppRule to startup the service before running any test.
**Warning:** It only grabs the first interaction from the pact file with the consumer, where there could be many. (This could possibly be solved with a parameterized test)
```groovy
class ReadmeExamplePactJVMProviderJUnitTest {
@ClassRule
public static final TestRule startServiceRule = new DropwizardAppRule<DropwizardConfiguration>(
TestDropwizardApplication, ResourceHelpers.resourceFilePath('dropwizard/test-config.yaml'))
private static ProviderInfo serviceProvider
private static Pact<RequestResponseInteraction> testConsumerPact
private static ConsumerInfo consumer
@BeforeClass
static void setupProvider() {
serviceProvider = new ProviderInfo('Dropwizard App')
serviceProvider.setProtocol('http')
serviceProvider.setHost('localhost')
serviceProvider.setPort(8080)
serviceProvider.setPath('/')
consumer = new ConsumerInfo()
consumer.setName('test_consumer')
consumer.setPactSource(new UrlSource(
ReadmeExamplePactJVMProviderJUnitTest.getResource('/pacts/zoo_app-animal_service.json').toString()))
testConsumerPact = DefaultPactReader.INSTANCE.loadPact(consumer.getPactSource()) as Pact<RequestResponseInteraction>
}
@Test
void runConsumerPacts() {
// grab the first interaction from the pact with consumer
Interaction interaction = testConsumerPact.interactions.get(0)
// setup the verifier
ProviderVerifier verifier = setupVerifier(interaction, serviceProvider, consumer)
// setup any provider state
// setup the client and interaction to fire against the provider
ProviderClient client = new ProviderClient(serviceProvider, new HttpClientFactory())
Map<String, Object> failures = new HashMap<>()
verifier.verifyResponseFromProvider(serviceProvider, interaction, interaction.getDescription(), failures, client)
// normally assert all good, but in this example it will fail
assertThat(failures, is(not(empty())))
verifier.displayFailures(failures)
}
private ProviderVerifier setupVerifier(Interaction interaction, ProviderInfo provider, ConsumerInfo consumer) {
ProviderVerifier verifier = new ProviderVerifier()
verifier.initialiseReporters(provider)
verifier.reportVerificationForConsumer(consumer, provider, new UrlSource('http://example.example'))
if (!interaction.getProviderStates().isEmpty()) {
for (ProviderState providerState: interaction.getProviderStates()) {
verifier.reportStateForInteraction(providerState.getName(), provider, consumer, true)
}
}
verifier.reportInteractionDescription(interaction)
return verifier
}
}
```
### An example of running provider verification with spock
This example uses groovy and spock to run the provider verification.
Again the provider service is a DropWizard application, and is using the DropwizardAppRule to startup the service.

pact-jvm-provider-spring_2.11 from group au.com.dius (version 3.5.24)
# Pact Spring/JUnit runner
## Overview
Library provides ability to play contract tests against a provider using Spring & JUnit.
This library is based on and references the JUnit package, so see [junit provider support](pact-jvm-provider-junit) for more details regarding configuration using JUnit.
Supports:
- Standard ways to load pacts from folders and broker
- Easy way to change assertion strategy
- Spring Test MockMVC Controllers and ControllerAdvice using MockMvc standalone setup.
- MockMvc debugger output
- Multiple @State runs to test a particular Provider State multiple times
- **au.com.dius.pact.provider.junit.State** custom annotation - before each interaction that requires a state change,
all methods annotated by `@State` with appropriate the state listed will be invoked.
**NOTE:** For publishing provider verification results to a pact broker, make sure the Java system property `pact.provider.version`
is set with the version of your provider.
## Example of MockMvc test
```java
@RunWith(RestPactRunner.class) // Custom pact runner, child of PactRunner which runs only REST tests
@Provider("myAwesomeService") // Set up name of tested provider
@PactFolder("pacts") // Point where to find pacts (See also section Pacts source in documentation)
public class ContractTest {
//Create an instance of your controller. We cannot autowire this as we're not using (and don't want to use) a Spring test runner.
@InjectMocks
private AwesomeController awesomeController = new AwesomeController();
//Mock your service logic class. We'll use this to create scenarios for respective provider states.
@Mock
private AwesomeBusinessLogic awesomeBusinessLogic;
//Create an instance of your controller advice (if you have one). This will be passed to the MockMvcTarget constructor to be wired up with MockMvc.
@InjectMocks
private AwesomeControllerAdvice awesomeControllerAdvice = new AwesomeControllerAdvice();
//Create a new instance of the MockMvcTarget and annotate it as the TestTarget for PactRunner
@TestTarget
public final MockMvcTarget target = new MockMvcTarget();
@Before //Method will be run before each test of interaction
public void before() {
//initialize your mocks using your mocking framework
MockitoAnnotations.initMocks(this);
//configure the MockMvcTarget with your controller and controller advice
target.setControllers(awesomeController);
target.setControllerAdvice(awesomeControllerAdvice);
}
@State("default", "no-data") // Method will be run before testing interactions that require "default" or "no-data" state
public void toDefaultState() {
target.setRunTimes(3); //let's loop through this state a few times for a 3 data variants
when(awesomeBusinessLogic.getById(any(UUID.class)))
.thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.ONE))
.thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.TWO))
.thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.THREE));
}
@State("error-case")
public void SingleUploadExistsState_Success() {
target.setRunTimes(1); //tell the runner to only loop one time for this state
//you might want to throw exceptions to be picked off by your controller advice
when(awesomeBusinessLogic.getById(any(UUID.class)))
.then(i -> { throw new NotCoolException(i.getArgumentAt(0, UUID.class).toString()); });
}
}
```
## Using a Spring runner (version 3.5.7+)
You can use `SpringRestPactRunner` instead of the default Pact runner to use the Spring test annotations. This will
allow you to inject or mock spring beans.
For example:
```java
@RunWith(SpringRestPactRunner.class)
@Provider("pricing")
@PactBroker(protocol = "https", host = "${pactBrokerHost}", port = "443",
authentication = @PactBrokerAuth(username = "${pactBrokerUser}", password = "${pactBrokerPassword}"))
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class PricingServiceProviderPactTest {
@MockBean
private ProductClient productClient; // This will replace the bean with a mock in the application context
@TestTarget
@SuppressWarnings(value = "VisibilityModifier")
public final Target target = new HttpTarget(8091);
@State("Product X010000021 exists")
public void setupProductX010000021() throws IOException {
reset(productClient);
ProductBuilder product = new ProductBuilder()
.withProductCode("X010000021");
when(productClient.fetch((Set<String>) argThat(contains("X010000021")), any())).thenReturn(product);
}
@State("the product code X00001 can be priced")
public void theProductCodeX00001CanBePriced() throws IOException {
reset(productClient);
ProductBuilder product = new ProductBuilder()
.withProductCode("X00001");
when(productClient.find((Set<String>) argThat(contains("X00001")), any())).thenReturn(product);
}
}
```
### Using Spring Context Properties (version 3.5.14+)
From version 3.5.14 onwards, the SpringRestPactRunner will look up any annotation expressions (like `${pactBrokerHost}`)
above) from the Spring context. For Springboot, this will allow you to define the properties in the application test properties.
For instance, if you create the following `application.yml` in the test resources:
```yaml
pactbroker:
host: "your.broker.local"
port: "443"
protocol: "https"
auth:
username: "<your broker username>"
password: "<your broker password>"
```
Then you can use the defaults on the `@PactBroker` annotation.
```java
@RunWith(SpringRestPactRunner.class)
@Provider("My Service")
@PactBroker(
authentication = @PactBrokerAuth(username = "${pactbroker.auth.username}", password = "${pactbroker.auth.password}")
)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class PactVerificationTest {
```
### Using a random port with a Springboot test (version 3.5.14+)
If you use a random port in a springboot test (by setting `SpringBootTest.WebEnvironment.RANDOM_PORT`), you can use the
`SpringBootHttpTarget` which will get the application port from the spring application context.
For example:
```java
@RunWith(SpringRestPactRunner.class)
@Provider("My Service")
@PactBroker
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class PactVerificationTest {
@TestTarget
public final Target target = new SpringBootHttpTarget();
}
```

Pact provider
=============
sub project of https://github.com/DiUS/pact-jvm
The pact provider is responsible for verifying that an API provider adheres to a number of pacts authored by its clients
This library provides the basic tools required to automate the process, and should be usable on its own in many instances.
Framework and build tool specific bindings will be provided in separate libraries that build on top of this core functionality.
### Running Pacts
Main takes 2 arguments:
The first is the root folder of your pact files
(all .json files in root and subfolders are assumed to be pacts)
The second is the location of your pact config json file.
### Pact config
The pact config is a simple mapping of provider names to endpoint url's
paths will be appended to endpoint url's when interactions are attempted
for an example see: https://github.com/DiUS/pact-jvm/blob/master/pact-jvm-provider/src/test/resources/pact-config.json
### Provider State
Before each interaction is executed, the provider under test will have the opportunity to enter a state.
Generally the state maps to a set of fixture data for mocking out services that the provider is a consumer of (they will have their own pacts)
The pact framework will instruct the test server to enter that state by sending:
POST "${config.stateChangeUrl.url}/setup" { "state" : "${interaction.stateName}" }
### An example of running provider verification with junit
This example uses java, junit and hamcrest matchers to run the provider verification.
As the provider service is a DropWizard application, it uses the DropwizardAppRule to startup the service before running any test.
Warning: It only grabs the first interaction from the pact file with the consumer, where there could be many. (This could possibly be solved with a parameterized test)
```java
public class PactJVMProviderJUnitTest {

public static TestRule startServiceRule = new DropwizardAppRule<DropwizardAppConfig>(DropwizardApp.class, "config.yml");
private static ProviderInfo serviceProvider;
private static Pact testConsumerPact;
@BeforeClass
public static void setupProvider() {
serviceProvider = new ProviderInfo("Dropwizard App");
serviceProvider.setProtocol("http");
serviceProvider.setHost("localhost");
serviceProvider.setPort(8080);
serviceProvider.setPath("/");
ConsumerInfo consumer = new ConsumerInfo();
consumer.setName("test_consumer");
consumer.setPactFile(new File("target/pacts/ping_client-ping_service.json"));
// serviceProvider.getConsumers().add(consumer);
testConsumerPact = (Pact) new PactReader().loadPact(consumer.getPactFile());
}
@Test
@SuppressWarnings("unchecked")
public void runConsumerPacts() {
//grab the first interaction from the pact with consumer
List<Interaction> interactions = scala.collection.JavaConversions.seqAsJavaList(testConsumerPact.interactions());
Interaction interaction1 = interactions.get(0);
//setup any provider state
//setup the client and interaction to fire against the provider
ProviderClient client = new ProviderClient();
client.setProvider(serviceProvider);
client.setRequest(interaction1.request());
Map<String, Object> clientResponse = (Map<String, Object>) client.makeRequest();
Map<String, Object> result = (Map<String, Object>) ResponseComparison.compareResponse(interaction1.response(),
clientResponse, (int) clientResponse.get("statusCode"), (Map) clientResponse.get("headers"), (String) clientResponse.get("data"));
//assert all good
assertThat(result.get("method"), is(true)); // method type matches
Map headers = (Map) result.get("headers"); //headers match
headers.forEach( (k, v) ->
assertThat(format("Header: [%s] does not match", k), v, org.hamcrest.Matchers.equalTo(true))
);
assertThat((Collection<Object>)((Map)result.get("body")).values(), org.hamcrest.Matchers.hasSize(0)); // empty list of body mismatches
}
}
```

Map clientResponse = (Map) client.makeRequest()
Map result = (Map) ResponseComparison.compareResponse(interaction.response(),
clientResponse, clientResponse.statusCode, clientResponse.headers, clientResponse.data)
then:
// method matches
result.method == true
// headers all match, spock needs the size checked before
// asserting each result
if (result.headers.size() > 0) {
result.headers.each() { k, v ->
assert v == true
}
}
// empty list of body mismatches
result.body.size() == 0
where:
interaction << scala.collection.JavaConversions.seqAsJavaList(testConsumerPact.interactions())
}
}
